GREASE-SEPARATOR.

SPECIFICATION forming part of Letters Patent N o. 735,192, dated August4, 1903.

Application filed March l0, 1903. Serial No. 147,189. (No model.)

To @ZZ 'Lu/"wm t may concern:

Beit known that I, RUDOLF ALLERT, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inGrease-Separators, of which the following is aspeciiication.

My invention relates to separators for removing oil or grease fromiiuids, such as eX- haust-steam, in which they are carried insuspension, and has for its object to provide improved means whereby toaccomplish this purpose by bringing the grease-laden duid into contactwith porous material and then draining the porous material of theabsorbed oleaginous substances, whereby fresh surfaces are constantlypresented to the action of the passing fluid.

With this object in view the invention consists in an apparatus of thischaracter, the improved construction, arrangement, and combination ofthe parts of which will be hereinafter fully described and afterwardspecilically claimed. r

The single figure in the drawing represents a separator embodying myinvention in central longitudinal section.

Referring to the drawing by letters, a is a chamber, in this instance inthe form of an upright cylinder, made of any suitable size and materialand provided with a suitable steam-inlet pipe b and outlet-pipe c, eachpipe being controlled by valves, as at d.

At e is shown a baffle-plate in the form of an upright cylinder, and thedrainage-chamber g is an annular chamber surrounding the same anddrained from a suitable point at the bottom. The steam is guided alongthe inside of the cylindrical bafe-plate c by spiral guides, as at m,the rotary motion imparted to the grease-laden fluid by said guidestending to throw out the minute particles of oil or grease and bringthem into contact with the cylindrical baffle-plate.

The outlet-pipe c is provided with a sidetrack pipe j, having valve 7e.The walls of the chamber may also when deemed desirable be provided witha non-conducting lining Z, for instance, of asbestos.

The operation of my device is as follows: The grease-laden steam is letinto the cham- Vfor that purpose.

ber a through the pipe b, its valve being open The outlet-pipe c isclosed, and the valve 7c of the side-track pipe j is opened. This drawsa current of steam through the apparatus for the purpose of heating thecylinder of porous material to prevent the subsequent condensation ofmoisture thereon. After this operation has continued until the cylinderof porous material is suiiciently heated the valve k is closed and thevalve of the outlet-pipe and the valve h of the drainage-pipe areopened.

The drainage-pipe, it will be observed, communicates with the outer air.The pressure on the outer side of the porous material will be lower onthis account than that on the inner side, against which the steam impinges. This difference in pressure insures the constant passage of theabsorbed oil through the cylindrical baffle-plate. If, however, thisdifference in pressure should not be sufficient, the pipef may beconnected with avacuum-pump or similar means for lessening the pressurewithin the drainage-chambers.

The grease or oil on the cylindrical bafdeplate 4of porous material isabsorbed thereby, is forced through the plate by the difference ofpressure, collects within the drainage-chamber, and is subsequentlyremoved through the pipe f.

In its passage through the porous material .the oil is filtered andpurified and can again be used for many purposes, the operation of theseparator thus accomplishing the manifold result of clearing theexhaust-steam of oily substances and purifying and saving such oilysubstances, which might otherwise be wasted.

I do not care to limit myself specifically to the use of a porousmaterial like earthenware. Any material having similar properties-as,for instance, charcoal, coke, asbestos, felt, dtd-may be employed, withresults depending upon the efficiency of the particular absorbing mediumused. This device is very efficient and takes out practically all of theoil from exhaust-steam and may be used for the removal of oily materialfrom ammonia or other fuid with equal success.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent of the United States, is-

IOO

l. In a grease-separator for eghau'st-steam and the like, asteam-chamber formed as an upright cylinder, in combination with acylinder of porous material mounted in the upright cylinder forming aninner steam-chamber and an outer grease-chamber, an inlet and outletsteam-pipe communicating with the inner steam-chamber, and agrease-drainage pipe communicating with the greasechamber, substantiallyas described.

2. In a grease-separator for exhaust-steam and the like, a steam-chamberformed as an upright cylinder, in combination with a cylind'er of porousmaterial mounted in the up'- right cylinder forming an innersteam-chamber and outer grease-chamber, an inlet and an outletsteam-pipe communicating with the inner steam-chamber, and aspirally-twisted guide-piece in the inner steam-chamber, substantiallyas described.

Witness my hand this 5th day of March, 1903, at Philadelphia, State ofPennsylvania.
